I disagree. The point is to save money by using an aircraft tailored to today's conflicts (and to be able to supply to allies), and to keep hours off the dwindling fleets of F-16s, F-15s and A-10s, and to 'season' younger less experienced pilots quickly and cheaply. The USAF is big enough to be able to afford a small but significant force of OA-X, which makes perfect sense, for them, to me.
